I own a glass company and we have installed countless mirrors especially tilt mirrors. Never have I had this much trouble with brackets sliding on the mirrors and coming loose and twisting. It’s a horrible design with too many moving pieces. It’s made out of 3 or 4 pieces and it’s all screwed together. So they all come out of alignment and twist and if the mirrors not sliding out of the bracket then the double sided tape piece in the back is sliding off. Absolutely terrible would not recommend to anyone.
